OIL-BURNER.

T0 @Z3 11171/0772, it 72mg/ concern.-

Be it known that We, BENJAMIN G. DEVOE and CHARLES W. BAILEY, citizens of the United States, residing at and whose postoflice addresses are Lima, in the county of Allen and State of Ohio, have invented new and useful Improvements in Oil-Burners, ot which the following is a specification.

This invention relates to oil-burners, and is particularly applicable for use in ranges or stoves, as well as furnaces.

The primary object of the invention is to provide a cheap, durable, and efticient burner for crude or similar oil which may be conveniently applied to an ordinary stove or furnace Without materially changing the construction thereof.

A further object is to provide an eilicient means for regulating the supply ot` air into the mixing-chamber, whereby the flame may be controlled.

Further objects, as Well as the peculiar details of construction embodied in this device, will be clearly described hereinaft.er, illus trated in the accompanying drawings, and defined in the appended claims, in which- Figure l represents a vertical longitudinal sectional view through a burner constructed in accordance with my invention, the supplypipe being shown in elevation. Fig. 2 is a horizontal section through the device in alinenient with the upper portion of the cone. Fig. 3 is a side elevation of the supply-pipe and the regulating-tube.

l designates the top of a stove or furnace in which is secured a hollow thimble 2. A feed or adjusting tube 3 is loosely mounted in this thiinble and has at its upper extremity a nut or head 4, the purpose of which will be described hereinafter.

5 designates a supply-pipe through which the oil is admitted into the feed-tube, and the amount of oil dispensed may be controlled by means of a valve 6, positioned at any convenient point intermediate the pipe 5.

On the lower extremity of the feed-tube 3 is arranged a threaded bur or boss, which carries an adjustable dome or hood 8, surrounding an aperture 9 in the lower end of said feed-pipe 3. This hood has formed at its lower end an upwardly and flaring flange l0, on which is arranged a plurality of equidistant ribs or partitions 11, alternating with a plurality of inclined ribs l2, secured tothe inner wall of the inner Haring walls of the oil-receiving chamber 13. This chamber 13 has a concentrically-arranged and upwardlyprojecting flange iu the form of a hollow truncated cone 11i, around the outer wall ol which is arranged a plurality ol ribs l5, upon which rest the wick-retaining supports lG. These supports are in the shape ol a bell and terminate at their lower extremities in troughshaped flanges 17,which receive wicks 1S,prel` erably cylindrical. These supports are arranged one within the other, and the upper one supports a wick of similar diameter to the lower one. In the drawings We have illustrated but two supports, although it is obvious that a greater number may be employed, if desired. A suitable fastening device 19 is designed to secure the supports rigidly together, and from its top is an upwardlyprojecting pin 20, upon which a pad of absorbing material 2l is secured. This pad is immediately below the aperture 9 of the feedtube 3, and as the oil drops upon the same it is distributed over the surface of the bell-shaped wick-supports, perfectlysaturating the upper wick, the excess of oil being conveyed over the trough-shaped flange onto the next or succeeding wick until all of them are perfectly saturated; A door 22 is provided in the dome S, whereby a taper or match may be inserted to ignite the oil. By turning the nut or head 4 of the tube 3 the bur 7 will turn within the threads ofthe dome 8 and raise or lower it, thus increasing or diminishing the distance between the ribs thereof and those upon the oil-pan, whereby the flame may be regulated. The air is admitted through the concentric conically-arranged flange 14, secured to the oil-pan, and passes between the ribs l5 into the dome, whereby it is mixed with the oil or gas before the same is ignited. As the oil flows from the pad 21 onto the bell-shaped supports the heat thereof will partially vaporize it, so that it will readily mix with the air admitted through the conc-shaped flange just described.

While we have illustrated but a single burner as applied to a stove, it is obvious IOO that a multiplicity may be used, if desired. This will particularly be true in the event that the burners be employed for furnaces.

Having thus fully described our invention, what we claim, and desire to secure by Letters' Patent, is-

1..In a device of the character described, the combination with an oil-chamber; of a plurality of wick-supports carried thereby, an adjustable dome or hood suspended over the supports, and a feed-tube communicating with and supporting the dome.

2. In a device of the character described, the combination with an oil-chamber having a hollow u pWardly-proj ecting and concentrically-arranged tube for the admission of air, a plurality of Wick-supports carried thereby, a dome arranged over said supports, anda feedpipe communicating therewith and adapted to adjust the dome toward and awayfrom the wick-supports.

3. In a device of the character described, the combination with an oil-chamber, provided With a concentrically-arran ged ai r-inlet at its bottom, a wick-support provided with an upwardly and outwardly aring flange arranged adjacent the walls of the oil-chamber, a dome suspended over the support, and a feed-tube communicating with said dome and adapted to adj ustably support the same.

4. In a device of the character described, the combination with an oil-chamber having a concentric air-inlet, a bell-shaped wick-support surrounding said inlet, a feed-tube arranged above the support and adapted to feed oil upon the same, and an adjustable hood carried by said pipe and surrounding the support.

5. In a device of the character described, the combination with an oil-chamber having an upwardly-projecting and concentricallyarranged tubular ange projecting from its bottom to form an air-inlet, ribs arranged on the outer walls of said flange, a bel1-shaped wick-support carried thereby and resting on the ribs, means for supplying oil to the wicks, and an adjustable hood arranged above the support and surrounding the same.

In testimony whereof we affix our signatures in presence of two witnesses.
